The Skeletal archer is one of the three undead adventurers of the skeletal trio boss, found in Daemonheim, his comrades being the Skeletal sorcerer and the skeletal warrior. He appears to be wearing a Sagitarrian armour set, along with a sagitarrian longbow and arrows. The skeletal trio is only available to members, in the occult floors. The level and life points of the archer (and his comrades) varies from each occult floor in Dungeoneering. Like his comrades, he will randomly use protection prayers to block incoming damage.
The skeletal archer can deal as much as 1000 damage at his highest level, so players using magic should use Protect from Missiles to reduce damage.

While he has no official weakness, using melee with high level armour is recommended because melee armour will reduce his chances of hitting.
